Kobelco loader arm part 1

Between Alistair123, IC Weld, C&C Equipment and CEE....You all make brilliant content with jobs that educate, entertain, and highlight problem solving skills. Great video so far Greg, can’t wait for PT 2 to drop

Everyone says the 500-ton shop-built press we have is overkill. But every once in a while we need all she has. Awesome video showing how to make what you have work. Cheers.

I found your channel watching Cutting Edge Engineering it was a suggestion after I watched CEE that was a few months back. Glad I clicked it I like heavy machinery repairs and welding. I served with the USAF for 25 years as a Jet Mechanic with experience on F-4, F-16,AWACS, KC-135R and B-52 aircraft. Now I’m 70% permanently disabled.

You had me backing away from my screen!

I heard stories about my uncle straightening things by running them over with other bigger things like a D7. Back then, not a lot of gear and equipment, so things were done in the field. He was pretty rough, so guys would try everything else before coming to him. Thanks for sharing this challenge. Lot of guys watching and learning.

That opening shot had me laughing out loud🤪🤣

Flying jig bits remind me of the lengths of talent to work on farm equipment when my Dad and GrandDad farmed. There was always something, and Granddad had a full hearth and blacksmith shop, so heating things up required stoking wood and coal. But I learned to weld and fabricate from GrandDad and watched his passion for old heavy iron. If I could do my dream job, it would be working on equipment while serving the Lord.

Once in a while things need to get sketchy , LOL . Really nice repair !

I bet your competitors weren’t queuing up to take this one on. The size of that repair was a David and Goliath. I got to thinking about the tool they use to weld railway line together. Loved this one Greg. Great job, thank you.

With this temper colors from the heat you brought in, I would think that the metal has lost some flexibility by now... 🤔 These flying parts from the press were scary...wow... Looking forward to part2, thx for showing! 👍👍👍

Amazing the amount of work you needed to get this to the point you can line bore it. I learn much from watching you Greg, and I am grateful to you for producing your videos. I don’t know if I’ll ever do that heavy duty welding or not, but having a frame of reference to refer to is a good thing. With what you had to work with, your problem solving really shines. I still admire the tonal quality of your voice….you probably have an untapped treasure there! 🙂

This has to be my absolute favorite so far, not sure why but the difficulty is what did it for me. That is brilliant finished product !

Love to see so many highly skilled tradesmen produce content. Hopefully this will encourage more people into the trades that are sadly lacking people. Great work!

*On Fire Welding* Bravo well done, thank-you sir for taking the time to bring us along. GOD Bless.

I enjoy watching your videos. Not a welder myself, but appreciate your skills. Learning much from you, I.C. Weld, and Cutting Edge Engineering. Thank you for sharing.

When I watch not just your channel but the likes of CEE and IC Weld, I get a sense of relief that im not the only one experiencing such difficulties. I run three workshops. Car mechanics were we cary out repairs, servicing, and MOT testing. Next door, i have the bodywork and fabrication shop with a separated, double paint spraying booth. Opposite these two workshops, i have what i call general engineering working with lathes and Mills. These are used for military contracts such as parts needed to build tanks and other armoured vehicles. Sometimes, what seems like the easiest of projects to complete turns out to be a total nightmare. With all the will in the world, you get to a point where nothing goes right, and the light at the end of the tunnel just seems to get further away. Like boys in the playground using their jumpers for goal posts only, they move them further away and closer together, making the task of scoring your goal that much harder. Strange analogy, i know. I guess what im trying to say is. No matter the journey taken to get to where you need to be, difficulties can always be overcome as all three of you guys have proven. Time and time again. The outcome with patience, thought, and dedication is that the projects always end up looking as they should do, perfect. I know, I know, I talk too much. Sorry people I look forward to seeing part two soon.👍⚒️🏴󠁧󠁢󠁥󠁮󠁧󠁿

Cee Curtis is the man! But I you are when it comes to the on-site repairs. Love your content and your explanation of what you're doing.

Nice work.. I found myself stepping back from my phone screen, way over here in Louisiana, when you were pumping the porta power with the ram... I've had them damn things fly, burst internally or actually break the base. My old ass is gun shy of them things... I've been off my tools lately after over 30 years in the fabrication trade and I'm enjoying your content.

Great Job. It is great to watch you and the below mentioned people work there repair magic. Keep up the good work.

Wow thats a good repair, the manner of that bend in that shaped material made it nearly impossible to to straighten with the tools you have available. Thats a great idea you have to make the start and finish of the welds neat & tidy.

That truly was amazing!! Great work, Greg!! By the way, I bought Florin Tractor’s 100 Ton Press, when they went out of business,the frame is massive, that’s what you need!! Keith Fenner built in my opinion, the best press I have ever seen! That might give you some good ideas ( Turn-Rite Machine Shop) I like the way all the press equipment is on top and encapsulated in case of a hydraulic leak!! I believe the series is “Press Talk”,Well thought out, I’ll bet you will do one better!! Thanks, Vic!!

I was figuring you would partially cut the problem ear off so it would be easier to line up. Weld a "jig" in the yoke so it would close to true when you welded it back up. I have had these types of repairs. Good job on the fix.

Greg, you need a Cold One after this...... PB

Great video, love seeing the different challenges… Looking forward to part 2 🥂

Amazing love that plasma,beveling,press and the bud rose torch too! The work you do l love it its my type of work love the challenges! U do a great job making it happen! ✌🏼👍

You guys got some huge beers out there, definitely a strong can to bend a church key that large.

Excellent decision to cut off the old and weld the new. This is exactly the way I would have done it 50 years ago. Sure, brings back a lot of memories. Pretty impressive welding truck you have also. Be nice to see a short video of a walk around of the truck and the way it is rigged. I will be back for part. #2

Brilliant video. This is first class engineering and fabrication. Looking forward to part 2. Thank you

You should absolutely go for a shop built press video series. I think following you as you create the "Ultimate" shop press would be the "Ultimate" video experience!!!

I had to do that for the bolt anchors on a D10. They hold down the weights. Tried a propane torch, took to long. Just gonna have to get them glowing cherry orange with a cutting torch and use the press. Once they were back to shape. We wrapped them heat blankets. Let them cool over night. Next day installed them back on. These things were bent beyond repair. There like 2 to 3 inches thick and 2 ft long. Your just gonna have to manipulate that glow and bend slowly to shape.

Looking forward to your new press build.

This is the kind of stuff I could have a blast with! Although I did have the thought of cut it off and replace it when I first saw the project. It was kind of cool seeing all the attempts to straighten it and how close you got. The other end of that to the floor might've given you you the leverage needed to finish the bend. But the final solution probably came out better than you could've ever gotten the other way. Really nice work !

Always amazed at your skills!! Great video.

Simply amazing! Looking forward to part two.

Keep up the great work Greg.

So far so good. I"m impressed mostly because I would have had the same equipment problem such as a press that could handle something like this. You adapted and overcame the problem. Love it. Keep on keeping on.

Awesome, challenging project! Great job.

This is a wild repair! The vast majority would’ve said no way. Kudos, man.

0:05 this looks like it's right up your alley. i can even hear a little snickering in your voice when you say "can I fix this". lol, yes.

Awesome job working tgat big huge arm you spent a lot of time on it and as always the outcome was well worth it I like how you don't rush you work you take time an look things through to make the job right ! 👍👍

I have the same beetle track torch it’s sweet. Never tried the plasma cutter in it. Will have to give it a try sometime. Thanks for sharing!

You, CEE, C&C Equip, and Perpetual make my playlist... Allstar Line-up...

Greg your talent is amazing. Like I have said I am just a old pipe welder

Love your channel!!! Really great content!

Im amazed it moved. Hats off!

First time I watched your channel I might be hooked

Nice work, and a very interesting job at that. It reflects how costly a new part would be, and if you could get it in reasonable length of time. Enjoyed, cheers!

Wow! Awesome job and video! Thanks for sharing! 👌👍

That's a lot of metal to bend back in shape. Cheers good job.

Some of us make those castings you keep bringing in the shop. I'd love if you could show the foundry logo on these castings, and part number, because there's a good chance we might have supplied them. We pressed the ears on these all of the time before final machining the castings.

Havent seen your channel before, but the yellow piece of metal doing a horse inpression in the thumbnail intrigued me.

Just passing through watching your video and reading the comments hoorah

That was the most challenging project I’ve seen you do. That was bent and warped. Maybe getting it red hot like blacksmith used to do then press straight??? Your method was very good too. Now line bore Really enjoy your channel

Neglect is what keeps you in business

Greg you the man brother. And Jacob too. OFW crew gettn r done.

As a non-specialist, since the initial aim was to preserve this "ear" without cutting and re-welding it, I wonder if reforging this "ear" might not be a good solution in this case ? But of course, you'll tell me that you need a forge, which isn't available everywhere for such a piece of metal ! Good job anyway, like nothing happened !! Rocks !!

Excellent repair. I'd love to see that press rebuild vid.

Love this video! So much great info!!!

Outstanding work as always , master welder/machinist

another nice repair , me personally would have used lincoln MC6 metal core wire no slag to clean up runs hot and fast and lays down nice and flat like that fluxcore and while you had the gouge out those 3/8 flat carbons were perfect to knock off those runoff tabs . i might have tacked a couple 3/4 round or flat to the outside of those ears to keep the spacing when you back gouged and welded the inside since you didnt use the spacer again you wouldnt think she move being that thick it turn out mint excellent job gregg and on to the next one

thank you so much for sharing every thing ! jesus bless you

“Can I fix this?”....that’s a good one...your funny

Lincoln makes the best dual-shield I've ever run,their new machines are not what they once were but I'm good for 2 rolls of 71Elite a week. Cool video man!

Greg, good stuff!

This was a great video and nice fix, Thanks.

Give that guy a Gold Star for twisting up that part. That took some doing... L0L. I was curious as to how you were going to un-twist that back into its original shape & location. Bending back is one thing. Twisted is a whole other beast unless you heat that steel to a rosy red color. Then at least you give yours a fighting chance. Looks good man. Well done.

You should throw piece of cable /chain on the press with safety hook. Save your rams if they kick out and you know it will only go the length of the cable. We do that for using center hole rams for when you snap 1 1/2 all thread when pulling seized picot pins🙄 . Great video bud 👍

I kinda miss playing with all the enerpac jacks/rams at my old job. One time we had a guy shear a 2" threaded rod with a 100ton ram trying to pull an insert out of a die bed. That baby shot 30' in the air to the ceiling.

Awesome as Always Cant wait for part 2

Great video, I like to use 2 rams on a project like that, one to hold the piece in place and one to do the pressing, Thanks

Great video, a head scratcher for sure but the other ear is a question mark for me. Maybe wish you had done two new ears some day! But time will surely tell Nonetheless a great fix, very nice welding.

Awesome job.

Bad A..!! Can't wait for the next!!!

Please include in your descriptions the machine the parts/repairs are for. It's nice to be able to go look at what it is.

A decent pair of channel locks and two bowls of Wheaties for breakfast, you could’ve bent that back straight by hand😁👍

what a process as always very good work a great thought process.

I wanted to start a pool as to when you'd cut that tab off. But you went down swinging and with that tear and cracking it was the only thing you really could have done. Excellent work. Now, where's part two?

I’m with knuckles, this story is fascinating. I would’ve thought that eye would have a crystalline issue anyway.

15:52 Noodling over a problem is an important part of the process.

If someone ever needed a visual representation of the concept that there’s nothing in this world that is beyond repair - this video.

While I give props for trying to straighten things, most of the folks that do repairs like this would have cut that bent sucker off and welded a new ear on like you eventually did. God job

Sleeping on a problem works well for me. I like to spend time thinking about how I’m going to solve it. When I’m pressing something that needs big pressure I will use something softer than the parent material it tends to lessen the part from getting spit out and killing me. lol. Pressing is a very dangerous activity. Love your content

For some good machining, straitening and press vidyas look up Keith Fenner at turnwright machine. He built his press and has some nice touches. Most of his straitening is precision on prop shafts but educational. Also a big oxy/propylene torch is my favorite for things that don’t fit in a gas forge, used to heat shrink to straiten and camber jib and bridge crane beams and tubes on trussed ones.

Fkn sweet. Love it. Thanks!

..."after I stared at it for an hr."..true and funny how that works!

I believe those are 4x4 billets used to make rod and wire. These are heated and ran through a dye and roller set up to produce a round shape then drawn out to form rods and wire for cable, nails, etc. I was a metalurgist for Bethlehem Steel and handled rod and wire products. These are formed from ingots in a blooming and slabbing mill. We made 4x4's and 2x2's for this purpose depending on what was intended as the final product. The arm you are repairing was more than likely forged using repeated hammer blows to form the shape and maintain strength. You might need to build a rig and devise a way to rapidly form the metal with quick blows. Heat can be used as well. The press will probably not yield the shape you need and will cause you to find the need to deviate from that effort.

Nice job sir. You'd have enjoyed working in the navy during WW2 fixing up battle damaged battleships and aircraft carriers!. Those guys did amazing work considering they had none of todays modern tools or materials.

205 👍's up on fire welding thank you for sharing 🤗

Ouch! Damn Doug quit tossing us around! I thought we were friends! lol

If you loop a sling or strap through the handle of the Enerpac ram and the eye of the ear it keeps it from flying for your head! lol I learned that the hard way…

You are crazy to do that man

nice 10 minutes of interesting content

Awesome job!!!!

I am trying to compute just how much hydraulic force it took to twist that giant piece of steel and snap the pin that was in there.

Subscribed! Great Channel!

23:30 I knew I had seen that track somewhere before, but could not remember what it was or where I had seen.... I think you are right about Kurtis using a Beetle..... but maybe Issac uses one too......

Very exciting when that jack went for a ride 🫨

To be able to bend it back without cracking it needs to be red hot. Your weed burner does not have enough juice. In South Texas we use a coil type head for burning the spines off catus so cattle can eat during droughts. Look up a coil pear burner, they still make them, this coil pear burner will put out a lot of heat.

I saw that coming that that bottle jack will pop out. In my mind i said you should have at least welded block around the jack just to secure it from doing exactly that. Luckily you were in the opposite side when it popped out

Would love if you could get an auto-darkening helmet/filter so I can see more detail during the welding itself Awesome work as always!
